Question

If the total area of a dartboard is 30,000 mm2 and the area of the second ring

is 15,000 mm2, what is the probability of landing in that second ring?

A. 30%
B. 15%
C. 20%
D. 50%

Answer 1

probability is 50 percent

Explanation:

total area= 30000

area of secknd ring=15000

therefore 15000/30000 times 100

equals 50 percent

Answer 2

Option D.

Explanation:

From he given information, we get

Total area of a dartboard = 30,000 mm²

The area of the second ring = 15,000 mm²

We need to find the probability of landing in that second ring.

`Probability=\frac{\text{The area of the second ring }}{\text{Total area of a dartboard}}`

`Probability=(15000)/(30000)`

`Probability=0.5`

Multiply the probability by 100 to find the percentage.

`Probability=0.5* 100`

`Probability=50`

Hence the correct option is D.
